### Question: What causes Restless legs syndrome?
### Response: Restless legs syndrome (RLS) occurs most often in middle-aged and older adults. Stress makes it worse. The cause is not known in most patients.
RLS may occur more often in patients with:
Peripheral neuropathy Chronic kidney disease Parkinson's disease Pregnancy Iron deficiency Use of certain medications
A form of RLS may be passed down in families. This may be a factor when symptoms start at a younger age. The abnormal gene has not yet been identified.
Restless legs syndrome can result in a decreased quality of sleep (insomnia). This lack of sleep can lead to daytime sleepiness, anxiety or depression, and confusion or slowed thought processes.
